ok you got to buy a new disc or try cleaning yeah i did that and solve it also if that didnt work buying a new memory unit and disconnect your hdd so now u dont have a hdd but you got a portable memory

It is possible that the information on the disk is corrupted. This can happen during production though it is rare. If you have the NXE dashboard you can try copying the disk to the hard drive. It usually doesn't copy if the data on the disk is bad. If you have an Xbox live Silver account or above you can also get the latest update for the game, which may solve your problem.
Alternatively, try another copy of the game.

hold down the sync button and turn on your xbox (while still holding sync) untill it boots all the way. now goto settings > memory > games > halo 3 and delete all downloadable content and boot halo 3 if you get an update allow it and if everything goes well you should be able to get to campagne and eveything then redownload all downloadable content. some updates mess with the DL content and the holding of the sync while booting clears all failed updates and redownloading should reconfig the files to work wih the update. Hope this helps.
